To .all @1J/tom t may concern:

Be 1t known that I, DAVID H. COLE, of

Portland, in the county 0f v full, by a description of the machine in all its parts and operation.

I construct a frame in the accompanying drawing A, A, A, Figure 1,three feet square, five feet high, with girders and posts, of four inch timber, the lower girders B, B, being two feet from the floor, on these I place the end of a cylinder, C three feet in diameter and two feet long, formed by connecting two wheels, D, D, in the accompanying drawing; with sixteen ribs, E E E equidistant, made of two inch timber, and cover the whole interior circumference with sheet iron C or some metallic substance, with small holes, or apertures, unched inwardly; on each end of this cylin er are iron circles, F one fourth of an inch thick, four and half inches wide, the outer edges form a. right angle, extending on the wood one inch, like angles on the inner edges form bevels, G, facing the iron covering. These circles are confined by rods and screws. In the center between two posts, I make an openin H, in the upper iron circle, one inch wide and three inches long. Directly under, and within one inch of this aperture, I commence the track of a circular inclined lane, I,I,I,pro jecting from the inner sur ace or the outer cylinder formed with rails of iron or composition one inch wide, and of suliicient length to reach two or more ribs, to which they are confined by screws or nails, the ends are connected by joints, this plane with a regular descent, is continued several times around the cylinder, until it reaches the lower iron circle; through which an opening J, like that above is made, and at its termination a other age sging accomplished without t-he loss or waste l puf 1 of grain. And to enable others Skilled inA such machinery, to make ,and use my im` provements, I will proceed to give them in stop is placed extending tothe rail above. Wi wheels and ribs, made of three inch t Uber, I construct a second cylinder K K Zand 3, two feet long, and 4of such diampter as will fill the space within that described, without friction on the inclined plane, at each end connected with the wheels is a cross-work, L, L, L, in the center of which is an iron shaft, M, two inches square, three and half feet long, the lower end pointed with steel, extends .six inches below the cuosswork, and stands in a composition box attached to a har N. The ends of this bar rest op extga ers framed into the este;

a oye the upper crossworiii), is a ten inches Lon and eight in difameter; the end aboveis tied to a box and hat like hose below; I reduce the diameter of each end of the inner cylinder two inches and place thereon iron hoops, P, one inch wide, with arms, Q let into them; the upper hook is sloped from the lower edge of the hoop to a bevel Q', of one inch. On the lower hook also is a bevel Q2 which covers the rim Q on the iron circle; the outer circumference of this cylinder is covered with sheet iron, or other metallic substance, with holes punched outwardly, and is put on in four equal parts, leaving a perpendicular space, R R, between each, half an inch wide. Four wings, L, L, forming a fan are placed between the two crosswise, extending from the shaft in opposite directions, to the sheet iron 0n the left of the spaces, on the right are ribs, standin obliquely, by which the inner width of the spaces' is increased two inches; at the lower end center of these spaces or ventilators, rest the points of wedges, S, S, the wide ends sloping upward. Above the opening in the upper iron circle and the post on the right, is a fan with four wings, eight inches square, attached to an iron shaft, T, one inch square, eighteen inches long, resting horizontally on iron knees U, U, fixed to the wood work; on the inner end of the shaft is a ulley, V, four inches in diameter, the cylin er, W, W, covering the pan is suspended to the wood work of the frame and connected with the shaft. A box, X, ten inches wide, eight inches deep and three feet long, containing two screws represented by the dotted lines, is placed across the frame with one end near the fan. Attached to this end of the box are two iron arms, Y, which extend to and rest on the shaft outside the cylinder, the other end elevated six inclfes isgsnspended vtotal; girdprat Z. At thelowei erid of the Linder siieve, is a conductor a leading to the opening H in the upper circle. At the outlet below, is a con` ductor, box with sieves, fan with shaft; pulley and cylinder, like those described above.

Two pulleys like those on the fan shafts, Fig. i2, are attached to the girders opposite, by iron gudgeons and `shafts six inches long. A small band is pressed aronnd the upper e'nd, of the large pnlley, andcarried over the whole frame resting'on the -oor small pulleys. A leather band four inches wide, placed on the lower end of the large pulley, and attached to a one horse power is sufficient to put the whole in motlon.

In operating, the grain falls from elevators on the upper sieve and passes through leaving all larger matter to escape at t e lower end. The wind from the fan, has a direction between the sieves, blowing off the dust. The small seeds fall from the grain, through the lower sieve. The motion of the box, caused by the arms resting on the shaft of the fan, shakes the grain from the lower sieve into the conductor, which directs it to the space between the cylinders. The wind from the fan of the inner cylinder, blowing thriigli'the ventilators, hastenfs it rapidly through the rnachine, on the circular plane to the outlet, where it is again operated 0n by the sieve's and fan below.

What I claim as new in said machine and the improvements which I desire to secure by Letters Patent, are- The particular manner of making and a1- rangin the circular inclined plane between the cylinders, and the manner of carrying the grain downward on said plane, by the combinedl power of wind and inclination, and in connection with this, the openings made in the circles, which admit and discharge the grain; the bevels on the circles and inner cylinder, which give the grain a direction from the joints, toward the plane above and the outlet below; the manner of connectingx the sieves and fans, resting the arms on t e sieve boxes on the shafts of the fans, by which both receive motionfrorn the same pulley.
